4.1.1 DRV8316T Compatibility
The DRV8316xEVM is compatible with the DRV8316T (H/W variant) as the featured motor driver IC to spin
a three-phase Brushless-DC motor. The DRV8316T replaces the SPI settings with five specific pin settings
(MODE, SLEW, OCP/SR, GAIN, and VSEL_BK) that can be adjusted through resistor dividers.
When using the DRV8316T, the SPI enable resistors in the “Depop. if DRV8316T” silk screen box are to be
depopulated (R9-R12) and the resistor dividers in the “Hardware Variant Resistors” silk screen box are to be
populated (R37-R46) with the desired settings.
Figure 4-4 shows this setup.
Table 4-3 shows the status of populated and DNP resistors for the two compatible DRV8316x variants. Table 4-4
shows the user-adjustable resistor divider settings when using the DRV8316T. R37-R41 resistors tie to AVDD
and R42-R46 tie to AGND. The defaults of the two tables are in bold.
